Ring by Koji Suzuki is a trip through the disturbing. It is not true horror like I had thought, and I think the movie was a bit different from the book (at least from what I remember from my teen years). I was never really scared, per say, but the book was just that level of... unnerving to be more terrifying than most. It was a little like the beginning of Salem's Lot by Stephen King. Creepy, but not scary.
The characters are good, but my favorite has to be Sadako, a character you never actually meet. I want to learn more about what her deal is, and I'm going to spending a bit of time to find the next book in the series, Spiral.
